32w5d + diarrhea

I always had constipation and for almost 3 days it feels like the first trimester (pee princess) and today I have a good surprise of diarrhea. They say it's a sign of near labor so I don't know. I'm also having very mild contraction or braxton hicks. It's still too early for me to deliver her but my first 2 kids were 37th week born. I couldn't tell too if my belly's dropped. Lol it feels like I'm a first time mom. My due is on Aug. 25.
